Do you know how to distinguish the quality of LED display screens? If you don’t know exactly, this video will give you an accurate answer. Below is the reference for judging.

1. Flatness: The surface flatness of high-quality LED displays should be within ±1mm, so that the displayed image will not be distorted.

2. Brightness: For indoor LED video walls, the brightness should be above 800cd/m², while the brightness of outdoor LED displays should be above 5500cd/m².

3. White balance effect: If there is a deviation in the actual proportion, the white balance will be biased, and the common problem is blue or yellow-green.

4. Color reproduction: A high-quality LED display screen should be able to accurately restore the color of the original image, so that the audience can get a real visual experience.

5. Mosaic and dead point phenomenon: Mosaic refers to the small square blocks that are always bright or always black on the display screen. Dead points refer to single points that are always bright or always black on the display screen.
